The concept of multi-principal elements has opened up prospects for the development of new high-entropy ceramics (HECs) suitable for extreme application environments such as advanced turbine engines

nuclear reactors

and hypersonic flight vehicles. High-entropy metal borides (HEBs)

as a new type of HECs

have high hardness

high-temperature strength

low thermal conductivity

and radiation resistance

making them suitable for use in the aerospace field. This study provides a detailed review of the preparation technologies of HEBs powders and ceramics

evaluating the advantages and disadvantages of different preparation methods. By reviewing the latest research progress in the field of super-hard ceramics and ultra-high temperature ceramics at home and abroad

the advanced position of HEBs in materials science is revealed. Future research directions of HEBs

such as advanced powder preparation technology

efficient ceramic sintering technology

machine learning

and computer simulation are discussed. This review provides scientific basis and technical support for promoting preparation

performance improvement and wide application of HEBs.
